USB Copy Protection

I need to have a solution that can COPY PROTECT my usb flash drive. That is anyone can execute or read files from my USB drive but cannot copy them from USB drive to any other drive/device. Your solution must preferably be lied on the USB drive. Means it must not be implemented on a specific PC. It must work wherever the USB drive is plugged. Kindly mention how you are gonna implement it and in how much time.
